⚠️ 𝗪𝗵𝗮𝘁 𝗗𝗼 𝗔𝗹𝗹 𝗧𝗵𝗼𝘀𝗲 𝗦𝘁𝗶𝗰𝗸𝗲𝗿𝘀 𝗼𝗻 𝗬𝗼𝘂𝗿 𝗖𝗼𝗻𝘀𝘂𝗺𝗲𝗿 𝗨𝗻𝗶𝘁 𝗔𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗠𝗲𝗮𝗻? (𝗔𝗻𝗱 𝘄𝗵𝘆 𝘆𝗼𝘂 𝘀𝗵𝗼𝘂𝗹𝗱𝗻’𝘁 𝗽𝗲𝗲𝗹 𝘁𝗵𝗲𝗺 𝗼𝗳𝗳!) ⚠️

Ever looked at your fuse board and thought: "What are all these warning labels for?"

Here’s a quick guide to the most common stickers you’ll see on a UK consumer unit — and why they matter:

⚠️ 𝗪𝗵𝗮𝘁 𝗗𝗼 𝗔𝗹𝗹 𝗧𝗵𝗼𝘀𝗲 𝗦𝘁𝗶𝗰𝗸𝗲𝗿𝘀 𝗼𝗻 𝗬𝗼𝘂𝗿 𝗖𝗼𝗻𝘀𝘂𝗺𝗲𝗿 𝗨𝗻𝗶𝘁 𝗔𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗠𝗲𝗮𝗻? (𝗔𝗻𝗱 𝘄𝗵𝘆 𝘆𝗼𝘂 𝘀𝗵𝗼𝘂𝗹𝗱𝗻’𝘁 𝗽𝗲𝗲𝗹 𝘁𝗵𝗲𝗺 𝗼𝗳𝗳!) ⚠️ - Plugs Electrical, High Wycombe

⚡ 𝟭. 𝗠𝗮𝗶𝗻 𝗦𝘄𝗶𝘁𝗰𝗵 𝗪𝗮𝗿𝗻𝗶𝗻𝗴 𝗟𝗮𝗯𝗲𝗹 "Warning Isolate Supply Before Opening Cover"
This reminds you that live parts are still present even with circuit breakers off and in order to isolate the whole supply the main switch should be in the off position.

⚡ 𝟮. 𝗥𝗖𝗗 𝗧𝗲𝘀𝘁 𝗟𝗮𝗯𝗲𝗹 "This installation, or part of it, is protected by a device......."
This tells you to test your RCDs every 3 months by pressing the ‘T’ or ‘Test’ button — it could save your life!

⚡ 𝟯. 𝗜𝗻𝘀𝗽𝗲𝗰𝘁𝗶𝗼𝗻/𝗧𝗲𝘀𝘁 𝗦𝘁𝗶𝗰𝗸𝗲𝗿 "This installation should be periodically inspected......"
Shows date of last inspection & recommended next inspection date. Domestic homes usually need one every 5 years if rented and 10 years if owned.

⚡ 𝟰. 𝗗𝗮𝗻𝗴𝗲𝗿/𝗪𝗮𝗿𝗻𝗶𝗻𝗴 𝗟𝗮𝗯𝗲𝗹𝘀 "This installation has more than one power supply..."
Used in special setups like solar or EV chargers — alerting electricians to hidden risks.

⚡ 𝟱. 𝗗𝗮𝗻𝗴𝗲𝗿/𝗪𝗮𝗿𝗻𝗶𝗻𝗴 𝗟𝗮𝗯𝗲𝗹𝘀 "Circuit No.s _ _ _ do not have provision for earthing metal equipment"
Indicates the lack of an earthing conductor usually in a lighting circuit and warns against installing metal class 1 light fittings.

⚡ 𝟲. 𝗗𝗮𝗻𝗴𝗲𝗿/𝗪𝗮𝗿𝗻𝗶𝗻𝗴 𝗟𝗮𝗯𝗲𝗹𝘀 "Safety electrical connection do not remove"
Used to alert individuals about the presence of an electrical safety connection, usually an earthing connection, that should not be disconnected.

⚡ 𝟳. 𝗗𝗮𝗻𝗴𝗲𝗿/𝗪𝗮𝗿𝗻𝗶𝗻𝗴 𝗟𝗮𝗯𝗲𝗹𝘀 "This installation has wiring colours to two versions...."
Alerts electricians to the use of both former (red/black) and harmonised (brown/blue)  cable colours within the installation.

✅ Top Tip: Never remove or cover these stickers they’re there to protect you, your family, and any future electricians working on your property.

    In December 2024 we needed an electrician to fit a built in Mircowave Oven which needed to be hard wired.

    We wanted a local business. We found Plugs in the Downley Magazine

    We made contact with PLUGS and our experience is as follows;

    Very quick response to us

    Made an appointment to view the work that would be required and attended

    Give us an estimate of the cost

    Advised when he could complete the work

    Arrived on the arranged appointment

    Took good care of our space with dust covers etc

    Very clean neat and tidy and excellent work

    When work complete we would not have known we had any work done

    Sent us an invoice

    Sent us a guarantee

    We liked the skills, qualifications and professionalism of it all

    We will definitely use Plugs again and will have no hesitation in recommending to our friends and neighbours.

    Needed an electrician to repair and refurbish fittings and wiring both inside and out. I had heard locally in Downley good things about Plugs which were confirmed online. Tony was straightforward and easy to deal with and carried out the work without fuss or mess. I will be using Plugs for a new installation I now need.

    I highly recommend Tony. We used him recently to do some work in our garage adding some sockets, a light and tidying up some messy cables going to the board.
    From my initial enquiry, he came round quick quickly and provided a detailed and fair estimate in a few days via email, listening to what I wanted and suggesting a few ideas to make the job tidier.
    I agreed a date for the work to be done, which it was, without any messing around. He arrived on time and worked in a very professional way, clearing up after himself. You could tell he knew what he was doing and gave confidence it would all be done as agreed and to a very high standard.
    I’d have no hesitation in using Tony/ Plugs electrical for any job, big or small

He always does a professional job and charges a fair price for quality work.

    Tony was highly recommended by both a friend and our bathroom fitter. He was very friendly and professional and provided a comprehensive quote. We haven’t proceeded with any work yet but we are confident his work would be carried out to a high standard.

    Tony of Plugs Electrical is helpful, knowledgeable, personable,  and competitive.  He even reduced his quoted price after the work he carried out didn't take as long as he had estimated. his work is thorough and to a high standard. He has carried out work both on our estate and in my home. I would thoroughly recommend him for all electrical works.
